Quality Control

Our Tetraammonium [[(2-Hydroxyethyl)Imino]Bis(Methylene)]Bisphosphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity and performance. Certificates of Analysis (COA) documenting key parameters such as assay, pH, and active content are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture, which may affect product quality.
